Xenophobia is a fear or distrust of foreigners. You can accept, and work to integrate, foreigners into your society while rejecting bad ideas. That’s the basis of modern multicultural democracies.
Xenophobia is a content-less word, made to be sounding like a medical condition, to justify bossing people around based on what they want or do not want in their country.
It is, of course, a white invention, as we feel morally superior enough to do all the bossing around. Let's call it the "white man's burden" to show those people how it should be done.
